Question

(x-2y)(y-3x)+(x+y)(x-3y)-(y-3x)(4x-5y)
​

Answer 1

Question :-

Simplify it

(x-2y)(y-3x)+(x+y)(x-3y)-(y-3x)(4x-5y)

Answer :-

→ 10x² - 14xy

Explanation :-

We have ,

(x-2y)(y-3x)+(x+y)(x-3y)-(y-3x)(4x-5y)

simply product of these

→(xy - 3x² - 2y² +6xy ) + x² - 3xy + xy -3y²

- { 4xy - 5y² - 12x² + 15xy}

arrange these ,

→ - 3x² +x² +12x² +xy +6xy-3xy +xy - 4xy

- 15xy - 2y² - 3y² +5y²

→ 10x² - 14xy
